Forms complex-shaped gas passages! It demonstrates significant effects on gas defects and burn-on occurring during casting manufacturing.
The "Spiral Pipe" improves gas venting of the core by embedding it in the core, preventing gas defects. Made of steel, it maintains a stable shape through bending processing and can form complex gas passageways. It is hard and resistant to crushing, preserving the shape of the gas passage. Additionally, the spiral structure absorbs thermal expansion, preventing the occurrence of bending, and allows for easy removal from the interior of the casting during mold disassembly. 【Features】 - Improves gas venting of the core by embedding it, preventing gas defects - Made of steel - The spiral structure absorbs thermal expansion, preventing bending - Easy removal from the interior of the casting during mold disassembly - Exhibits significant effectiveness against gas defects and burning that occur during casting production *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Other Features】 ■ Gas defects and burning are primarily caused by the oxygen in the air contained in the mold material expanding when heated. This product is simple and effective for creating pathways for oxygen. ■ The cavity of the core is less likely to collapse and is harder for sand to enter compared to Saran string. ■ It is also possible to pull out the spiral pipe after the core molding is completed. ■ When combining cores with different diameters, connecting spiral pipes of varying sizes allows for efficient gas venting. *For more details, please refer to the PDF document or feel free to contact us.
